How to change the console 12v source to always have power?
Does anyone know how to rewire the center console 12v power source so it has power when the car is turned off. I like to use it to charge my phone or MP3 player while the car is off.

Yes after the car has been shut off for like half an hour it goes in to a "sleep" mode.

Even if they are monitoring battery current, it's not going to pick up something as small as a cell phone charging. We're talking about tenths of an amp MAX. If they're really moitoring battery current, it would have to be a monitoring circuit capable of reading about 100 amps. You're not going to get milli-amp resolution out of something like that. I doubt they do current monitoring on anything other than the charging circuit anyway. |

The car usually knows which modules are causing excessive current draws. If you splice into an unknown module, it will cause problems.
Performing any kind of electrical modifications on these cars is not a good idea, especially if you don't know how the different systems interact. Splicing into what you think is a 12V source could cause all kinds of bus problems. |

It can read very little draw. I've worked on a lot of vehicles professionally and very minute voltage draws can cause interesting problems in a vehicle. It's very likely that milliamps could prevent sleep-mode. I'm not particularly familiar with the system, so I can't say with certainty, but it is definately not out of the realm of possibilities.

Look, I'm an electrical engineer. There's no reason the lighter can't be powered all the time to charge a cell phone. The computer in the car draws that much current even when it's in sleep mode. |

Wow I didn’t mean for my question to become a heated conversation. I think I will go to the dealer and talk to one to the techs and see what they say. I will update if I find out any info.
Thanks for all the posts though.
